2. Vibrational Spectroscopy ... Most infrared spectra are displayed on a linear frequency scale, as shown here, but in some older texts a linear wavelength scale is used. A calculator for interconverting these frequency and wavelength values is provided on the right.

An important tool of the organic chemist is Infrared Spectroscopy, or "IR". IR spectra are acquired on a special instrument, called an IR spectrometer. IR is used to gather information about compound's structure, assess its purity, and sometimes to identify it.

Infrared spectroscopy is the study of how molecules absorb infrared radiation and ultimately convert it to heat. ... infrared spectroscopy, only the electric field associated with the electromagnetic radiation is important and we will limit our present discussion to how this field varies with time. We called the light...

Interpretation of Infrared Spectra ... The interpretation of infrared spectra involves the correlation of absorption bands in the spectrum of an unknown compound with the known absorption frequencies for types of bonds. This table will help users become more familiar with the process.

Introduction to Infrared Spectroscopy. When a beam of electromagnetic radiation of intensity Io is passed through a substance, it can be either absorbed or transmitted, depending upon its frequency, n, and the structure of the molecule it encounters.

Infrared spectroscopy uses a machine, like a computer, that hits a substance, or in the case of forensic science an analyte (questioned substance), with infrared rays. The machine then records the wavelengths that the substance absorbs.
